Hi Dears,
Its a good place to get advice. I am working on MASTER Airborne
Simulator data. I have georeferenced various Scenes using GLT
technique. The scenes has moderate haze with clear weather. Turbulence
is (Winds from 320 degrees at 19 knots). I don't want to lose the
radiance of pixels as I am interested in converting pixels radiance to
pixel temperatures.
My concern are:
1. Does I need to apply FLAASH module for Atmospheric correction of
scenes given the above conditions?
2. If yes. Does Radiance values will be affected. As I mentioned, I
don't want to loose the Radiance values.
3. While doing ENVI's FLAASH tutorial for correcting AVIRIS data, on
step number 4 it is mentioned to select AVIRIS_1998_scale.txt file.
Where can I find similar file for my MASTER data?
AND Lastly,
4. Following step 6 of the same tutorial AVIRIS scale factors between
1995 and 2003 are said to 500 for the first 160 bands and 1000 for the
remainder. Where can I find the Scale Factors for my MASTER scenes?
Thank you for your earlist respose.
Best Regards,
Muhammad Arshad

Dear Devin:
WOuld you kindly suggest how to supply to filter function file from
calibration report. I have downloaded the spectral response curves for
my data.
Regards,
Arshad
